Synopsis
cast crabwalk [<victim>]
Description
Velocimancy is treated as something of a joke by most institutional magical researchers, but that is more a failure of imagination than anything else. A clever mage with a talent for bestiamancy invented crabwalking, which enchants a victim's legs so that they can never travel north or south, and instead are forced to move side to side forever. Or at least until the enchantment wears off.
